Hello,
I'm preparing to rebuild a pair of N1200S out of a pair of Sunn PA speakers, as one of the HF driver no longer works in one. It's a D130F/LF175 8 ohm two way, and I've noticed mention of a 16 ohm system as well...
I have a schematic for the N1200, sans S designator, that calls out 16.5uf, 12uf and 13.5uf for C1,2 and 3 respectively. Attached is a gutshot of the bad x-over, those caps are going away. I'm having trouble deciphering the value from that code, and am not inclined to trust actual measurement of a 40 year old paper cap.
What are the nominal values of C1,2 and 3 for an 8 ohm system? What I have printed in the N1200 schematic?
Dead stock or improved x-over point suggestions both appreciated.
